[0002] Against the backdrop of today's booming global trade, air transport, with its significant advantages of speed and timeliness, plays an indispensable role in the efficient transportation of temperature-sensitive goods such as pharmaceuticals. As a key piece of equipment to ensure the quality stability of such goods during air transport, the performance of refrigerated containers directly affects the quality of the goods and the economic benefits of transportation.

[0003] Traditional refrigerated air containers face numerous challenges in their design and use. Currently, good thermal insulation performance is a major weakness of traditional refrigerated air containers. In order to maintain a low-temperature environment inside the container, traditional containers rely heavily on continuous refrigeration equipment, which undoubtedly increases energy consumption and transportation costs significantly. During long-term transportation, if the refrigeration equipment malfunctions, the temperature inside the container will rise rapidly, causing the goods to deteriorate and be damaged, resulting in huge economic losses.

[0004] Therefore, developing a new type of aviation refrigerated container to address the need for efficient and effective insulation of goods is of significant practical importance and has broad market prospects. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Refrigerated air containers, such as Figures 1 to 9 As shown, the device includes a box body 1. A hinge 23 is installed on one outer wall of the box body 1, and a box door 2 is fixed to the hinge 23 by means of hinge. The box door 2 and the box body 1 are connected by a locking assembly. A sliding mechanism is installed on the inner wall of the top and the inner walls of both sides of the box body 1. A steel pipe 13 is welded to the inner wall of the bottom of the box body 1, and a placement seat 12 is welded to the top of the steel pipe 13. A phase change material 9 is installed in the sliding mechanism and the gap between two adjacent steel pipes 13 by means of sliding.

[0033] In this embodiment, the container 1 is formed by splicing and welding multiple plates. Its outer plate can be made of high-strength weather-resistant steel or hot-rolled ferritic stainless steel, and the inner plate can be made of SUS304 stainless steel or aluminum plate to ensure the strength, corrosion resistance and heat insulation performance of the refrigerated container. The gap between the inner plate and the outer plate can be filled with high-efficiency heat insulation materials such as polyurethane foam, polystyrene foam or glass wool, which have low thermal conductivity and good heat insulation performance, effectively reducing heat transfer and maintaining the stable internal temperature of the refrigerated container.

[0034] The pallet (not shown) can be placed using the placement seat 12. The pallet can be used to place goods that need to be refrigerated. The pallet makes it easy to use forklifts to pick up and put the goods from inside the box 1. The phase change material 9 can be placed from different directions using the slide mechanism and the gap between the two adjacent steel pipes 13. The phase change material 9 absorbs or releases a large amount of latent heat through the phase change process between solid and liquid. When the ambient temperature rises to the melting point, the material absorbs heat and melts to store energy. When the temperature drops to the freezing point, it releases heat and solidifies to release energy. Its own temperature remains constant when its physical state changes, thereby forming a wide temperature platform in a passive way to achieve long-term heat preservation and reduce the cost of use.

[0035] The locking assembly includes a locking head 21, a mounting clamp 22, and a rotating rod 24. The mounting clamp 22 is fixed to the outer wall of one side of the door 2 by riveting, and the rotating rod 24 is rotatably connected to the inner wall of the mounting clamp 22. The two locking heads 21 are respectively welded to the top and bottom of the rotating rod 24. The locking assembly also includes a limiting seat 4 and a fixing seat 3. The fixing seat 3 is fixed to the outer wall of one side of the box 1 by riveting. The limiting seat 4 is integrally formed on the surface of the fixing seat 3 and the limiting seat 4 and the locking head 21 are used together.

[0036] After the refrigerated goods are placed, the door 2 is rotated along the body 1 via the hinge 23 to gradually close the door 2. When the door 2 is completely closed, the drive rod 24 rotates along the mounting clamp 22. During the rotation, the end of the clamp 21 gradually moves to fit against the inner surface of the limiting seat 4. When the clamp 21 and the limiting seat 4 come into contact with each other, the limiting seat 4 limits the clamp 21, preventing the door 2 from opening along the body 1 and ensuring the stability between the body 1 and the door 2.

[0037] A card seat 26 is riveted to one side of the outer wall of the box door 2. A positioning plate 27 is rotatably connected to one side of the outer wall of the card seat 26 via a rotating shaft. A bracket 5 is welded to the side wall of the rotating rod 24. A toggle handle 25 is rotatably connected to the inner wall of the bracket 5 via a rotating shaft. A card slot is provided at the bottom of the card seat 26 to cooperate with the toggle handle 25.

[0038] The lever 25 and bracket 5 facilitate the control of the rotating rod 24. When it is necessary to control the rotation of the rotating rod 24, first rotate the positioning plate 27 along the card seat 26 to move it to the desired position. Figure 7 In the state shown, the lever 25 is then rotated along the bracket 5 to disengage the lever 25 from the slot at the bottom of the card seat 26. Then the lever 25 is rotated laterally, and the rotating rod 24 can be rotated by the connecting action of the bracket 5. The rotating rod 24 is used to control the separation or engagement between the card head 21 and the limit seat 4, thereby locking or unlocking the door 2 and the box body 1.

[0039] Both the bottom of the positioning plate 27 and the bottom of the card holder 26 are provided with lock holes 20;

[0040] When the lock hole 20 at the bottom of the positioning plate 27 is rotated to align with the lock hole 20 at the bottom of the card holder 26 and the lever 25 is located in the slot at the bottom of the card holder 26, the locking bar of the lock (not shown) is inserted into the lock hole 20 at the bottom of the positioning plate 27 and the lock hole 20 at the bottom of the card holder 26 in sequence, and the lock is locked, which can be used for theft prevention of refrigerated goods.

[0041] The slide mechanism includes a guide plate 8, a guide plate 16, and a top guide seat 17. The guide plate 8, the guide plate 16, and the top guide seat 17 are fixed to the top inner wall and the inner walls on both sides of the box 1 by riveting.

[0042] The phase change material 9 is guided by the guide plate 8, guide plate 16 and top guide seat 17, so that the phase change material 9 is installed by insertion and remains in contact with the inner surface of the box 1.

[0043] The inner walls of both sides of the box 1 are welded with side plates 15, and a fixing rod 14 is welded to the outer wall of one side of the side plate 15.

[0044] After the pallet and goods are placed on the placement seat 12, the fixing rod 14 is used to secure the straps to ensure stability. The straps can be used to fix the pallet and goods to the placement seat 12.

[0045] A mounting groove 19 is provided on one side of the outer wall of the box 1, and a temperature sensing hole 18 is provided between the mounting groove 19 and the box 1. A thermometer 10 is fixed inside the mounting groove 19 by embedding.

[0046] To facilitate temperature monitoring inside the enclosure 1, a thermometer 10 can be installed using the mounting slot 19. The temperature probe on the thermometer 10 monitors the temperature inside the enclosure 1 through the sensing hole 18. The thermometer 10 integrates a wireless transmission module such as Wi-Fi or Bluetooth. After the temperature probe measures the temperature data through the sensing hole 18, the internal circuit of the thermometer processes the data and then transmits the data in the form of a wireless signal to a remote receiving device such as a mobile phone, computer, or dedicated monitoring terminal through the wireless transmission module, thereby realizing remote temperature monitoring.

[0047] A support base 7 is welded to the bottom of the box body 1;

[0048] The housing 1 can be supported by the support base 7.

[0049] The inner wall of the guide plate 8 is equipped with a placement frame by means of suspension. The placement frame includes a mounting frame 11 and a hanging rod 6. The mounting frame 11 and the hanging rod 6 are fixed together by welding.

[0050] The mounting bracket 11 can be used to place the phase change material 9. After the pallet and the goods are placed on the placement seat 12, the mounting bracket 11 is hung on the guide plate 8 at the bottom by the hanging rod 6. The mounting bracket 11 can be used to increase the number of phase change materials 9 installed and improve the heat preservation effect.

[0051] Working principle: Goods are placed on a pallet, and the pallet is then precisely placed on the placement seat 12. The fixing rod 14 is used to wrap the straps around the goods to ensure they do not shake or shift during transport. Simultaneously, phase change materials 9 are installed through the gap between the sliding mechanism and the adjacent steel pipe 13. These phase change materials 9 utilize the phase change process between solid and liquid states to absorb or release a large amount of latent heat when the ambient temperature changes, thus forming a stable temperature environment for long-term insulation. Before transport, the box door 2 is closed, and the handle 25 is rotated, causing the rotating rod 24 to rotate, making the locking head 21 tightly fit with the limiting seat 4 to lock the box door 2. The thermometer 10 is embedded in the mounting slot 19, and its temperature probe senses the internal temperature of the box 1 in real time through the temperature sensing hole 18. The measured data is processed by the internal circuit of the thermometer 10 and then transmitted wirelessly to remote receiving devices such as mobile phones and computers via a wireless transmission module, facilitating monitoring by staff at any time.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
